I rnnurm'ric CUSHION FOR VEHICLES.

1 Specification'of Letters Patent.

Patented July 28, 1908.

Application filed. January 9, 1908. Serial No. 409,928.

To all whom it may concern:

Be it known that we, EDWARD A, GARVEY and CHRISTOPH R A. GARVEY, citizens of the United States ofAmerica, residing in the city of St. Louis and State of Missouri, have invented certain newand useful Improvements-iniheumaticCushions for Vehicles, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part .of'this specification. 3 v

Our invention relates to a pneumatic cushion for use in vehiclesas a medium for receiving the shocks to which the vehicles are subjected during their use upon roadways,

and the members of the vehicle directly associated therewith. Fig. V is an enlarged longitudinal section taken throu h oneend of the central portion of the cus 'on, and the members of the vehicle directly associated with the cushion. Fig. VI is an enlarged end elevation of the cushion and the members associated with it inthe vehicle. Fig. VII is an enlarged cross section taken on line VIP-VII, Fig. V.

In the accompan in nates the ground wheels of a ve fcle and an axle of the vehicle mounted in said ground wheels.

C is the vehiele body frame. I v

D are radial arms connected to the "body frame and to the axle B and having extensions D that extend outwardly from the axle toward the end of the vehicle.

E are the main vehicle s rings attached to the body frame C and t e inner arms of which are suitably connected to the radial arms D.

F. are saddles connected to the outer arms of the main s rings and provided at their upper ends wit shoes G. These saddles are united by a bridge piece I'I'.

ortions of t e vehic e drawin s: A desi I is a cushion carrier mounted. upon the radial arni extensions- D and J are links connecting thebodyframe C to this carrier.

No lnvention per se is herein claimed for the structural features of thevehicle just described they being set forth entirely for the vpurpo'seof showing the manner in which our tubular pneumatic cushion, which forms the subject matter of the present im rovement' is supported and carried in a. vehic e."

Referring now to o ur tubular. neumatic cushion: 1 designates the inflatab e sections of the cushion which are preferably two in number, so arranged, end to end, as to pro-,

duce a cushion of capsular shape, each section having one closed outer 'end and one open inner end. The cushion sections 1 may be of rubber or any other'pliable material'.

that is sufficiently impervious or rendered sufficiently impervious to the passage of air therethrough from the interior of the cushion sections to the exterior thereof, when the cushion sections are united in the manner to be described.

2. (see Fig. V) designates a circumferentially grooved hollow main union member that is adapted to be interposed between the .them and which may be tightly clamped around the open inner ends of said cushion sections by the employment of suitable means, such as bolts, as indicated in dotted lines'Fig. V;

It will,be seen that I scribed, serves to unite the cushion sections to each other in a manner to com lete the pneumatic cushion for utility,'so t at when air is forced thereinto, the cushion sections will be inflated and will remain in an inflated condition, when the pneumatic cushion is subjected topressure in-a vehicle for shock absorbing purposes. The pneuniatic cushion may be inflated by air introduced through a nipple 6 that is preferably seated in the the union made, as de- I ig. VII. This band'i's union member 2 and through which coinlnunication to the interior of the cushion 1S furnished, by the provision of a duct 2 extending to the interior of said union member. To provide for the attachment of the pneumatic cushion to the carrier I of the vehicle, we utilize a band -7 that encircles the central portion of the main union member 2" and which may, 'for convenience, oe com osed of sections bolted together, as seen in I referahly attached to the, carrier I by a llolt 8, see Figs. V and VII. r

We claim 15\ 1-. A pneumatic cushion for vehicles havmg a cushion-carrier, comprising afpair-of. cushion-sections each having an 0 en inner end, a main coupling having nec means for securing the bpen inner ends of said cushion-sections tothe decks of said main coupling, and means for securing the main 'coupling to the cushion-carrieiz 2. A pneumatic cushion. for vehicles having a'cushion-earrier, comprising a pair of cushion-sections each having a closed outer Y end and an open inner end, a main coupling having necks, means forsecuring the open inner ends of said cushion-sections to the necks of said main c0upling,'and means for securing the main coupling to the cushioncarrier.

3. A. pneumatic cushion for vehicles having a cushion-carrier, comprising a pair of cushion-sections each having an 0' on inner end, a main coupling having nee (s and a circumferential groove, means for securing the'open inner ends of said cushion-sections to the necks of said main coupling, a band encircling and located 1n the circumferential groove of said main coupling, and a bolt for securing the band to the cushion-carrier.

4. A pneumatic cushion for velncles having a cushion-carrier, comprising a pair of cushion-sections each having an open inner EDWARD A. GARVEY. CHRISTOPHER A. GARVEYL In presence oi"- BLANOHE HOGAN, LILY Rosr.
